SHEET-DELIVERY APPARATUS FOR PRlNTlNG-PRESSES.'

SPECIFICATION forming part of Letters Patent No. 316,189, dated April21, 1885.

Application filed February 5, 1884. (No model.) i

To aZZ whom it may concern.-

Beit known that I, .WALTER Sco'rT, of Plainfield, in the county of Unionand State of New Jersey, have invented an Improvement inSheet-Delivering Apparatus for Printing- Presses, ofwhich the followingis a specification.

This invention is made for separating the printed sheets from a web ofpaper and delivering them in such a mannerthat the first sheet is takenoff at one place and the second sheet at another place, and the distancethat the first sheet has to travel is suchthat when its advancing endreaches a given point the advancing end of the second sheet will havearrived at the same point, and the two sheets will be laid one upon theother, and so carried to the folding and delivery mechanism. I alsoprovide a cutter, which separates the two sheets longitudinally, andcombine with the same delivery mechanism that directs the double sheetsupon each other, so as to carry four out sheets laid on each other'tothe folding mechanism or to deliver such cut sheets laid one on theother, two to one folding mechanism and two to another foldingmechanism. By this means newspapers especially can be cut and laidtogether in the proper manner previous to the folding and delivery ofthe same.

In the drawings, Figure 1 is a side elevation of the apparatus. Fig. 2is a plan View of the folding apparatus and the devices for carrying thesheets into the same, Fig. 3 is an elevation of the end of the foldingapparatus. Fig. 4 represents the cutting-cylinders near one end. Fig. 5is a section ofthe delivering rollers and guides to deliver the sheetsin opposite directions, and Fig. 6 is a section of same with guide todeliver the double sheets upon each other in one direction.

. The frame-work A B is of any suitable character for receiving thecylinders and other parts-hereinafter described. The'cylinder 0represents the type or printing cylinder, and the cylinder D theimpression-cylinder.

The paper, after being printed in any desired manner upon the web, isbrought to the cutting-cylinders E F. The cylinder E contains the cutter6' with a serrated edge to separate the paper in any desired manner. Thecylinder F is twice the diameter of the cylinderlE, and contains twoslots, a [9, into which the cutter e passes in separating the sheets. Atthese slots (L and b are transverse notches, as shown in Fig. 4, thatallow'the grippers g h upon the respective cylinders G H to pass in andcatch the advancing end of the respective sheets and grasp the same andconvey the said sheets away. The cylinders G and H are the same diameteras the cylinder E, and the grippers on the respective cylinders G Hare-so placed and actuated that the advancing end of the first-sheet iscarried around by the pins2 to the grippers g on the cylinder G, andtaken off by such grippers and cylinder. The'advancing end of the secondsheet is taken by the grippers h of the cylinder H. The grippers areclosed by springs, as usual. Thecam y will open the grippers as theycome around each revolution and allow themto close at the proper time.They, however. will not grasp a sheet each time, as one sheet is carriedoff by the grippers h beforereaching the grippers g. It is necessary,however, to open the grippers it only every second revolution, to effectwhich I employ a cam, h, upon a' lever, h", pivoted at 5 and moved by aneccentric upon the shaft of the cylinder D, so as to .be brought intothe path of the Wrist or crank of the grippers every second rotation ofthe cylinder H.

There are belts around the cylinder G, passing over the roller It; alsobelts Z passing under the roller Z, over Z", along horizontally to theroller n up over the roller Z down and al'ong horizontally and over theroller Z and down 'to the roller Z. There are also belts 0 around thecylinder H, over the roller m, under the roller 0, over the rollers 0 0and back over the roller 0 to H. There is also a roller, p,witl1 acentral cutter, p, acting in a central peripheral groove in the roller Zto slit up longitudinally the paper that is carried through between therollers Z and p. There are also belts it around the roller 19, extending.to and passing around the roller if.

It is tobe understood that these respective belt-rollers may be full andparallel sided rollers, or they may be pulleys, as shown, in the'placeswhere the belts are to come, and that these pulleys and belts may becloser together or farther apart or more or less numerous than shown.

There is a guide-mouth for the paper, composed of the bars 6,with curvedends 7 ,which are stationary in the positions shown, and the bars 8,having curved ends 9, which bars are supported by the cross-shaft I,which is provided with a holding crank-arm, t, and apin, 10, which maybe entered into one of the two holes shown. When entered into the lowesthole the bars 8 will be sustained horizontally and parallel with thebars 6. When the pin 10 is entered in the upper hole the bars 8will beinclined so that their ends 9 come near to or in contact with the bars6.

From the foregoing description it will be understood that when the partsare in the po sitions shown in Fig. 1 the sheet that is held by the pins2 passes on until it arrives at the grippers g, and by them it is takenand car ried around to the belt Z. Here the grippers are opened, and thesheet is taken by the belts 7c and Z up to the cylinder or roller 1, andat the same moment that the advancing edge of this first sheet reachesthese rollers p and Z the advancing edge of the second sheet reachesthesame place, and one sheet is laid on the other, and the two arecarried on together between the belts land at, and as they go forwardthe rotary cutter p separates such two sheets longitudinally.

Upon reference to Figs. 1, 4, and 7 it will be seen that the groove atZ) in the cylinder F is made wider than usual in femalecuttingcylinders, the object being to allow the grippers h of thecylinder H to bend down'without injuring the back end of the first sheetsufficiently to get under and grasp' the advancing end of the secondsheet. If this alone were made use of, the cutter itself might press thepaper down into the groove without cutting it. I therefore introduce inthe groove b of the cylinder F the standing blade b, of sheet metal,which supports the paper while being cut, the knife 6 passing in behindsuch blade 1) into the narrow part b of the groove. This is shown moreclearly in the detached and enlarged view, Fig. 7. This blade I) isnotched the same as the blade a"(shown in Fig. 4) at the places wherethe gripper-fingers it pass along to run under the edge of the sheet ingrasping the same.

It is to be understood that one of the grooves in the cylinderFisprovided with pins 2, that hold the advancing end of one sheet, andthat, there are no pins at the other groove, because the advancing endof the other sheet'has to be taken off by the gripper upon the cylinderH.

The second sheet in reaching the rollers Z and 19 has been carried bythe grippers h around to the roller m, and there liberated and taken bythe tapes 0 over the roller m, under the roller 0, and projected alongover the bars 6 and below the bars 8 to such rollers Z and p; but if thebars 8 are moved, as aforesaid, so that the curved ends 9 rest upon thebars 6, said curved ends 9 will deflect the advancing end of the sheetupwardly, and it will be taken off between the belts 0 and 0 and overthe roller 0", and horizontally to second delivery apparatus, (not shownin the drawings,) but which is similar to the devices hereinafterdescribed with reference to the sheet as it is conveyed off between thebelts Z and n.

The folding-cylindersrr are similar to those in any ordinaryfolding-machine, and the folding-blade s is upon an arm, 8, whichreceives motion at the proper time from the cam 8, lever 8 androck-shaft 8*, upon which the arm 8 is affixed. I

t t are belts passing around the respective pulleys t i t, and t andthese convey the sheet along above the rollers 1' r and beneath thecreaser 8. These parts also are similar to those used in ordinaryfolding-machines, and-there'- fore do not require further description;and I remark that after the sheets have been folded by the blade 8 andcylinders r r they may be folded a second time, if desired, by the usualmeans.

One of the features of my present invention relates to the peculiarmechanism that intervenes between the belts l and n and thefolder,'whereby the sheets are directed to the folders.

j There are two cylinders, u u, below the belts l and at. These receivea constant rotation from the shaft P through the bevel-gears 20 21,shaft 22, bevel-gears 23 24, and gears 25 26 27 28, or by any othersuitable gearing. Above these cylinders u u there are the two rollers 12o in'frames 12 that are guided attheir ends in vertical slides c, andbetween them is a blade or director, 1;, which is fixed in the frame,and may be a single blade, as seen in Fig. 6, or atwo-part director, asseen in Fig. 5. Upon the frame 1) there are rack-teeth 35, and upon therock-shaft 0 there are segmental gears e the teeth of which gear withthe rack' 35, and to one of the gears o a rod, 36, is connected to alever, 'v", upon the rock-shaft 37, and upon the shaft P there is a cam,39,. that gives motion to the frame a through the arm o rock-shaft 37lever o rod 36, segments 0 rock-shaft c and racks 35, to raise and lowersuch frame, rollers, andblade, and the cam is shaped so as to give themotions at the proper time, and such cam may be grooved; or there may bea spring, 40, to press the lever o to the cam 39.

The sheets of paper, divided up longitudinally by the cutter p,pa'ssalong upon and between the belts l and n, and the advancing edges arearrested against the fence 4:1. The

sheets are either single or double, as before described. Thelongitudinal separation comes directly beneath the bladeo, and thesheets are below the rollers 11 o and above the rollers u a, and theselatter rollers u a are revolving constantly; hence when the frame 12rollers c e, and blade 12 are carried down by the sectors 12 theblade 1) passes down and bends the adjacent edges of the sheetsdownwardly between the rollers 10 a, and the moment the rollers 11 1;press the sheets upon the rollers u a the rotation of the latter causesthe sheets to be carried down between the two rollers u a.

The fences 41 aid in rendering the folding accurate. However, they maybe dispensed with if the creasers and drop-rollers are accurately timedto act upon the sheets.

If a single guide-mouth, w, formed of sheet metal or bars, is made useof, as shown in Figs. 3 and 6, then one sheet is laid against the other,and the two or four sheets are laid one upon the other as they pass downbetween a a and t if and off between the belts t t and beneath thefolding creaser or blades. Their movement is stopped by a fence at 46,and the creaser s is brought down to carry the sheets down between therollers r r to give to them the additional fold.

If the two part mouth w w composed of sheet metal or bars, as shown inFig: 5, is made use of, the two-part blade or director 12 (shown also inFig. 5) is adapted to pass down at each side of the central divider, 50,and carry the edges of the sheets downwardly, and

cause them to be conveyed through the mouthsconveyed away separately tofolding-machines,

or one sheet may be laid upon the other previous to arriving at thefolding-machine, and also the sheets, whether single or double, can beconveyed away to the folders either separately, or one sheet or one pairof sheets laidupon the other sheet or pair of sheets, and conveyed awaytogether to the folder or folders. This gives to my delivery apparatus acapacity to adapt the machine to newspaperwork, or to the printing ofbooks or other matters where the sheets are separately folded anddelivered.

I remark that, wherethe press is not of a width to require the use ofthe cutter p to separate the sheets longitudinally, the cylinders andgrippers may-be employed eXactly as described to bring the second sheetdirectly upon the first sheet, so as to carry them in this condition tothe folding-machine. If the cutter p is removed, the single sheet, orthe two sheets when laid one on the other, will pass along below thedrop-rollers 'v v, and the blade or director o will act with the rollersv v to carry the single or double sheet down between the rollers u a andfold the same, and

folding appliances, as before.

WVhen the tapes 0 0 are not used, the tapes a should be carried back andpass around the roller 0. In this case the guideibars 8 will not berequired, and the roller p may be dispensed with.
